技术领域Technical field

本申请涉及电子设备技术领域，尤其涉及一种画面显示方法及电子设备。The present application relates to the field of electronic device technologies, and in particular, to a screen display method and an electronic device.

背景技术Background technique

随着手机等电子设备的普及以及电子设备功能的日益丰富，很多用户喜欢长时间使用电子设备。但是，电子设备的显示屏产生的蓝色光谱(简称蓝光)对用户眼睛有一定损伤，长期使用会导致多种眼病发生。With the popularity of electronic devices such as mobile phones and the increasing functionality of electronic devices, many users prefer to use electronic devices for a long time. However, the blue spectrum (referred to as blue light) generated by the display of the electronic device has certain damage to the user's eyes, and long-term use may cause various eye diseases.

为了滤除或减少蓝光，现有技术通常采用如下方法：采用应用了红绿蓝(Red Green Blue，RGB)三基色发光二极管(Light Emitting Diode，LED)技术的液晶屏。由于RGB LED技术未使用传统的蓝光激发荧光粉的发光原理，而是采用红、绿、蓝三光复合发光。因此，蓝光在光谱中的能量比率大大降低。但采用RGB LED技术的液晶屏的成本很高。或者，在电子设备中安装特定软件，当该软件开启时，能够把显示屏中的蓝色分量全部滤除，但滤除蓝光后会使电子设备的整体显示效果偏黄。又或者，通过在电子设备上贴特殊的膜，利用膜片滤除蓝色光谱分量。但这种方法同样会导致电子设备的整体显示效果偏黄。In order to filter out or reduce blue light, the prior art generally adopts a method in which a liquid crystal panel using Red Green Blue (RGB) three-color light emitting diode (LED) technology is used. Since the RGB LED technology does not use the conventional blue light-emitting phosphor light-emitting principle, it uses red, green, and blue three-light composite light. Therefore, the energy ratio of blue light in the spectrum is greatly reduced. However, the cost of a liquid crystal panel using RGB LED technology is high. Alternatively, the specific software is installed in the electronic device, and when the software is turned on, all the blue components in the display screen can be filtered out, but the overall display effect of the electronic device is yellowed after filtering the blue light. Alternatively, the blue spectral component is filtered out by the membrane by attaching a special film to the electronic device. However, this method also causes the overall display effect of the electronic device to be yellowish.

综上所述，现有技术中的滤除蓝光的方法存在成本高或者虽然能滤出蓝光但对显示效果影响较大的问题。In summary, the method for filtering blue light in the prior art has a problem of high cost or a large effect on the display effect although the blue light can be filtered out.

Subprocessor's processor and display components. As shown in Figure 2, the method includes:

步骤201、电子设备确定待显示画面所包含的内容的类别。Step 201: The electronic device determines a category of content included in the to-be-displayed screen.

其中，待显示画面包含的内容可能为文字、数字、符号、动画、图片、视频等。一般来说，在显示动画、图片以及视频时，为了达到良好的显示效果以保证用户体验，需要减少色彩失真，尽量保证色彩的还原，也即这类内容对显示时的色彩要求较高。而在显示文字、数字、符号等字符时，字符的主要作用在于显示其本身要表达的含义，也即对色彩的要求相对于前类内容较低。因此，按照显示时对色彩的要求不同，可将待显示画面包含的内容划分为字符和非字符。其中，字符包括文字、数字、符号等。非字符包括动画、图片、视频等。The content to be displayed may be text, numbers, symbols, animations, pictures, videos, and the like. In general, when displaying animations, pictures, and videos, in order to achieve a good display effect to ensure the user experience, it is necessary to reduce color distortion, and try to ensure the color reproduction, that is, such content has high color requirements for display. When displaying characters such as characters, numbers, symbols, etc., the main function of the character is to display the meaning to be expressed by itself, that is, the requirement for color is lower than that of the former class. Therefore, the content contained in the picture to be displayed can be divided into characters and non-characters according to the color requirements when displayed. Among them, characters include characters, numbers, symbols, and the like. Non-characters include animations, pictures, videos, and more.

步骤202、当包含第一类别的待显示内容时，电子设备在显示所述待显示画面时，减少所述第一类别的待显示内容所在区域的蓝光分量。Step 202: When the content to be displayed of the first category is included, when the electronic device displays the to-be-displayed image, the electronic device reduces the blue component of the region where the content of the first category is to be displayed.

其中，第一类别的待显示内容为对色彩要求较低的显示内容，包括文字、数字、符号等字符。The content to be displayed in the first category is a display content having a lower color requirement, including characters such as characters, numbers, symbols, and the like.

以电子设备为手机为例，本申请实施例提供的方法可应用在以下应用场景中。Taking the electronic device as the mobile phone as an example, the method provided by the embodiment of the present application can be applied to the following application scenarios.

例如：当用户使用手机打开某个纯文本状态的应用时，如小说、文档等，采用本申请实施例的方法确定整屏显示均为文本，则整屏都进行滤除蓝光处理。For example, when the user uses a mobile phone to open an application in a plain text state, such as a novel, a document, or the like, using the method of the embodiment of the present application to determine that the entire screen display is text, the entire screen is filtered to remove the blue light.

当用户使用拍照、视频等应用并且全屏显示的时候，采用本申请实施例的方法确定整屏均为非字符，则不做滤除蓝光处理。When the user uses an application such as a photograph, a video, or the like and displays the image in full screen, the method of the embodiment of the present application determines that the entire screen is a non-character, and the Blu-ray processing is not performed.

当用户使用一些文字和图片、视频混排的应用时，采用本申请实施例的方法确定出每个内容所在的区域，如果是图片区域和/或显示视频的区域，则不做滤除蓝光处理，如果是文字区域则做滤除蓝光处理。When the user uses some text and image and video mixing applications, the method of the embodiment of the present application determines the area where each content is located, and if it is a picture area and/or a video display area, the Blu-ray processing is not performed. If it is a text area, it will filter out the blue light.

本申请实施例提供的画面显示方法，当需要显示画面时，根据待显示画面中包含的内容的类别，降低第一类别内容所在区域的蓝光分量后才显示画面。该方法通过仅对待显示画面的部分区域进行滤除蓝光处理，能够在保证良好的显示效果的前提下，减少蓝光对用户的伤害，达到较好的用户体验。In the screen display method provided by the embodiment of the present application, when the screen needs to be displayed, the screen is displayed after the blue component of the region where the content of the first category is located is reduced according to the category of the content included in the screen to be displayed. The method performs the filtering of the blue light only on the partial area of the display screen, and can reduce the damage of the blue light to the user under the premise of ensuring a good display effect, and achieve a better user experience.

为了更清楚的说明本申请实施例提供的方法，如图3a所示为未进行任何过滤蓝光处理的待显示画面，按照显示内容可以划分为7个区域，其中，区域1、3、7为文字区域，区域2为视频区域，区域4、5、6为图片区域；采用现有技术的滤除蓝光的方法，对所有区域都要进行滤除蓝光处理(图中以灰度表示进行了滤除蓝光处理)，得到如图3b所示的待显示画面；采用本申请实施例提供的方法仅对区域1、3、7等文字区域进行滤除蓝光处理(图中以灰度表示进行了滤除蓝光处理)，得到如图3c所示的待显示画面。其中，实际应用中，图3b所示的对整个显示画面都进行蓝光处理后的显示画面，其整体显示偏黄，显示效果较差；而采用本申请实施例提供的方法处理后的图3c所示的显示画面其整体显示效果与图3a所示的未进行任何蓝光处理的待显示画面差异较小，但实际上文字部分已经进行了滤除蓝光处理，有助于保护用户的眼睛。In order to more clearly illustrate the method provided by the embodiment of the present application, as shown in FIG. 3a, the to-be-displayed picture without performing any filtering blue light processing may be divided into seven areas according to the display content, wherein the areas 1, 3, and 7 are characters. Area, area 2 is a video area, and areas 4, 5, and 6 are picture areas; using the prior art method of filtering blue light, all areas are filtered by blue light (filtered in grayscale representation in the figure) Blu-ray processing), to obtain a picture to be displayed as shown in FIG. 3b; using the method provided in the embodiment of the present application, only the text areas of areas 1, 3, and 7 are filtered to remove blue light (the gray level representation is filtered in the figure) Blu-ray processing), the picture to be displayed as shown in Fig. 3c is obtained. In the actual application, the display screen after the blue light processing is performed on the entire display screen as shown in FIG. 3b, the overall display is yellowish, and the display effect is poor; and FIG. 3c processed by the method provided by the embodiment of the present application is used. The overall display effect of the displayed display screen is less different from the image to be displayed without any blue light processing shown in FIG. 3a, but in fact, the text portion has been subjected to filtering blue light processing, which helps to protect the user's eyes.

由于待显示画面包含的不同内容具有不同的特征。因此，基于不同内容有不同的特征，在步骤201的一种可能实现方式中，可以采用模式识别的方式，确定待显示画面中具体包括哪些内容。该过程具体包括：The different content contained in the picture to be displayed has different characteristics. Therefore, based on different characteristics of different content, in a possible implementation manner of step 201, pattern recognition may be used to determine that the display is to be displayed.

步骤1、获取待显示画面中包含的待显示内容。Step 1. Obtain the content to be displayed included in the to-be-displayed screen.

其中，在显示待显示画面之前，电子设备会获取待显示画面的内容并缓存，因此可从缓存区中获取待显示内容。The electronic device acquires the content of the to-be-displayed screen and caches the information to be displayed, so that the content to be displayed can be obtained from the buffer area.

步骤2、提取待显示内容的特征。Step 2: Extract features of the content to be displayed.

步骤3、基于待显示内容的特征，进行模式识别，确定待显示内容的类别。Step 3: Perform pattern recognition based on characteristics of the content to be displayed, and determine a category of the content to be displayed.

在该过程的具体实现中，由于计算机分别对字母、数字、汉字等字符定义了不同的表示方法，例如：对于中文，由于其种类较多，常用则有6000以上，可以将ASCII表的高128个很少用到的数值以两个为一组来表示汉字，即汉字的内码。而剩下的低128个则留给英文字符使用，即英文的内码；得到了汉字的内码后，还仅是一组数字，为了在显示器上显示文字，还需要结合文字的字摸，字模也是一组数字，是用数字的各位信息来记载英文或汉字的形状。因此，可根据字符的不同表示方法识别出字符。对于图片，则可以根据信号波形匹配得到。显示器识别待显示的是字符还是非字符的具体实现过程可参考现有技术，本申请实施例不再赘述。In the specific implementation of the process, the computer defines different representation methods for characters such as letters, numbers, and Chinese characters. For example, for Chinese, because there are many types, there are more than 6000 commonly used, and the height of the ASCII table can be 128. The rarely used values represent the Chinese characters in two groups, that is, the inner code of the Chinese characters. The remaining lower 128 are reserved for English characters, that is, the English internal code; after the internal code of the Chinese character is obtained, it is only a set of numbers. In order to display the text on the display, it is also necessary to combine the word touch of the text. The font is also a set of numbers, and the shape of the English or Chinese characters is recorded by the digit information. Therefore, characters can be recognized according to different representation methods of characters. For pictures, they can be matched according to the signal waveform. For a specific implementation process of the display to identify whether a character or a character is to be displayed, reference may be made to the prior art, and details are not described herein again.

现有技术中提供了多种模式识别的算法，因此，模式识别的具体实现可参考现有技术，本申请实施例不再赘述。A plurality of algorithms for pattern recognition are provided in the prior art. For the specific implementation of the pattern recognition, reference may be made to the prior art, and details are not described herein.

通过上述步骤1至3，本申请实施例提供了一种通过模式识别的方法确定待显示画面中包含的待显示内容的类别的处理方法。该方法具有通用性，可针对任意类型的待显示画面。Through the above steps 1 to 3, the embodiment of the present application provides a processing method for determining a category of content to be displayed included in a to-be-displayed image by a method of pattern recognition. This method is versatile and can be used for any type of picture to be displayed.
